Abstract

Seawater is one of the largest natural resources and abundant in Indonesia, which contains salt, metals and mycobacteria. Even though the amount is abundant, its utilization is still not widespread, such as to be used as clean water or drinking water. The use of adsorbents aims to adsorb impurities in the fluid. The adsorption column that is widely used is in the form of a fixed-bed column with messy stacked filling. This makes it difficult to clean and fill the adsorbent, besides the irregular pile of adsorbents will hinder the flow process of the purified fluid. The research product is a circulating portable adsorption column design consisting of 3 parts, namely: top distributor, packing bed, and bottom collector. The principle of the three parts is like a puzzle where the number of packing beds can be adjusted according to the purification needs. The three parts are connected with threads so that they can be disassembled as desired. It is hoped that this product can meet the needs of adsorption-based purification that is easy, inexpensive, and can be customized according to various types of adsorbents. The design of this product can be duplicated for other adsorption purification processes, such as purification of bioethanol, wastewater, and biodiesel.

Abstract

PT. Sewangi Sejati Luhur, a palm oil plantation company, manages 7,000 hectares divided into 12 divisions across 3 estates. The company primarily focuses on cultivating and processing Fresh Fruit Bunches (FFB), with the harvesting unit employing the most workers. This research aims to investigate the implementation of the Occupational Health and Safety (OHS) program within the harvesting unit at PT Sewangi Sejati Luhur, designed to prevent work accidents and occupational diseases. Conducted in Tapung Hulu Subdistrict, Kampar Regency, Riau Province, the study employs a quantitative descriptive method using the HIRARC method to assess OHS application and employee working conditions. A saturated sample of 30 harvesting employees was surveyed through interviews and documentation of the OHS program. The findings reveal that the OHS program includes periodic health exams, OHS awareness campaigns, monthly activities, and training sessions. The program's implementation has led to low accident rates and satisfactory achievement of goals. Correlation analysis shows a significant link between OHS program implementation and improved employee working conditions. Additionally, 82% of respondents reported that the OHS program significantly influenced their working conditions, while 18% cited other factors. Overall, the OHS program in PT Sewangi Sejati Luhur's harvesting unit has been effective, ensuring a low accident rate and meeting monthly targets.
